CHARLES W. SOULE, OF BOSTON, MASSACHUSETTS.

CARBURETED-GAS REGULATOR.

SPECIFICATION forming part of Letters Patent No. 245,981, dated August 23, 1881.

Application filed May 31, 1881. (No model.)

To all whom it may concern:

Be it known that I, OHAnLEs W. SoULE, of Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvements in (Jarbureted-Gas Regulators, of which the following is a specification.

This invention relates to apparatus for regulating the component parts of gas produced from the vapor of light hydrocarbon oil and air forilluminating purposes; and the objects of the invention are to provide automatic adjustin g-valvesto regulate the proper proportions of gas and common air in the illuminating-fluids supplied to the burners under varying pressures, so as to maintain a uniform light, whether few or many burners are in use.

Heretotore in illuminating with this gasoline-gas, which is commonly produced by forcingorblowing air through a carburetor wherein hydrocarbon-oil vapor mingles with the air, forming gasolinegas, it, as it comes from the carburetor, is generally too rich in carbon to be burned economically or to produce the best illuminating effect, and therefore requires dilution with common air. This dilution has heretofore been eflected by an air-supply pipe leading directly from the air-pump or blower to the pipe that conducts the gasoline-gas to the burners, and has been regulated inits volumeby hand manipulation, which rendered the same very unsatisfactory, as in supplying the proper proportions of gas and common air to one hundred burners at the required pressure, if alarge proportion of them were extinguished, the pressure upon the remainder would be too great. This defect or objection 1 overcome by the construction, combination, and arrangement of variable automatic adjustable valves with the gas-inlet pipe and the common-air-innecting-rods, so as to open or close more or less the ports formed in the air and gas conducting pipes by the vertical movement of the diaphragm arranged to rise and fall by the varying pressure of the gas within such apparatus but as such mechanism must necessarily be complicated and expensive and liable to be disarranged and rendered inoperative, my invention is designed to overcome these and other objections.

The figure in the drawing represents a vertical central section of a carbureted-gas regulator.

A represents a tank or vessel in which the carbureted gas and air are mixed; and in order that the varying pressure may be regulated, I provide the same with an adjustable top portion, B, as heretofore. This top portion is in the form of a smaller inverted vessel, its rim or edge of the mouth being received within an annular channel, 0, provided around the interior of the top portion or mouth of the outer vessel, A, and supplied with water, glycerine, or other suitable liquid to form a seal against the escape of gas therefrom, the carbureted gas being conducted therein from a carburetor by means of the pipe E, the inner end of which is curved downward, and the passage of the gas therefrom is automatically regulated by the action of the conical valve D, attached to the pivoted arm F, which is pivoted atits movable end to the lower end of the vertical operating-rod H, which passes upward above the top, mouth, or channel 0 of the said vessel A, and is bent at right angles and passes downward within said channel, and thence beneath the lower edge of the said adjustable top portion, B, where it is bent so as to return upward through said channel 0, and connected with a projection or ear, G, and is provided with a screw-thread and thumb-nut, J, so as to per mit the relative positions of the valve and its seat or end of said pipe E and the said adjustable top portion, B, to be regulated or adjusted through the means of said bent rod H and its thumb-nut resting upon the projection of the automatic adjustable top portion, B, whereby the vertical movement of the said top portion is made to automatically adjust said valve D.,

K represents an air-inlet pipe, the top or open end of which extends upward to a point near the top of the vessel A, and is provided with a conical valve, L, attached to the pivoted arm M, the movable end of which is pivoted to the bent rod N, which likewise passes downward through said channel, and thence upward to the top portion, where it is connected to a projection, P, and provided with a screw-thread and thumb-nut, R, whereby the valve of the air-tube may be adjusted and regulated so as to admit more or less air therein, as occasion may require, and when left the vertical movement of the said top portion, B, will automatically regulate the quantity of air as the pressure within the regulator increases and diminishes. By this simple, inexpensive,

variable adjustable device the proper proportions of carbureted gas and common air are regulated automatically, so as to produce a uniform light at all times at the burners connected with the exit-pipe T, as heretofore.
